OICA views concerning thermal propagation risks and the need for testing to evaluate such risks.

Proposal to include visual/audible inspections of batteries and pass/fail criteria throughout the electric vehicle safety test procedures in order to address risks associated with the release of flammable and toxic gases intended to relieve internal pressure and avoid battery ruptures or explosion.

At the 8th EVS GTR IWG meeting in Changchun, members of EVS Task Force 1 continued to discuss proposed requirements and test procedures (EVS-08-17) to address the safety performance of EVs during in-use in events of flooding and vehicle washing. As an action item, members were requested to provide comments on the overall proposal, specifically, water depth (10cm) and vehicle speed (20 km/h) for the drive test. The US believes that a 10 cm water depth test presents a reasonable and likely scenario for testing electric vehicle performance.

NHTSA recommendations for the state-of-charge of the energy system of plug-in and fuel-cell vehicles at the time of testing and on the conditioning procedures prior to testing.

Automaker organization comments on the NHTSA views (see document EVSTF-06-07), including differences in the application of the procedures under self-certification and type-approval regimes.

JRC position accepting the NHTSA views (document EVSTF-06-07) on the state-of-charge levels prior to testing (i.e., 95% for externally charged systems and 90% for fuel cell vehicles) and openness to revised language related to the draft “48-hour elapsed time prior to testing” provision.

Proposed revisions to the text concerning safety provisions for electrified heavy-duty vehicles.

Report on Chinese vibration testing of battery packs on commercial vehicles.

China comments on requirements for low battery energy warning telltale.

Status of the task force work.

This document summarizes data and information gathered by the JRC relevant to the risks of flooding (e.g., passing through standing water) to electric vehicles, in particular with regard to conditions found within the European Union, towards reaching an agreement on test conditions under the GTR.

JRC presentation in support of a one-hour post-test (post-crash) observation period for electrolyte leakage.

China-Japan agreement on draft text for the thermal propagation test procedure.

US proposal for sequential fault testing of battery management systems.

EC JRC views on the regulatory text proposed by the US concerning battery management system functionality (document EVS-09-05) and based upon the US draft sequential testing protocol (document EVS-06-36) which addresses the following tests:

• Extreme temperature protection (failed cooling and heating systems)
• Over-discharge protection
• Over-current and over-voltage overcharge protection
• External short circuit protection

Test protocol as of September 2015, covering vibration test, thermal shock and cycling, and mechanical integrity.

Agreed draft text concerning test procedures for mechanical impact and external short circuit protection.

Working draft for mechanical integrity crush force testing and evaluation for electrolyte leakage, fire, and explosion risks

Presentation of OICA views on the NHTSA, JRC, and Japan input regarding the state-of-charge of the batteries (or other energy storage systems) under electric vehicle safety testing.

EVS Task Force 5 includes testing for thermal propagation risks.
